Patented Aug. 2, 1932 STATES ERVIN IA. KELLEY, OF KANSAS CITY, MISSOURIWATER WELL scREnN Application filed March 12, 1932. Serial No. 598,336.

My invention relates to improvements in a water well screen.

The object of my invention is to provide a sectionally arranged screen,separable with respect to the sections.

A further object of my invention is to provide a screen consisting of aplurality of sections having an annular wall and a plurality of seatsspaced therearound as means to stack the sections in axial alignment.

A still further object of my invention is to provide a water well screencomposed of a plurality of members having an annular funneled wall witha flange on the end thereof, and a plurality of lugs spaced therearoundfunctioning as a'seat for the sections as stacked, and each lug havingvertically aligned therewith a tongue, and means to connect the samewith the corresponding lug portion of the adjacent section, each sectionbeing axially aligned and the adjacent upper and lower ends thereofbeing spaced apart and lapped to'provide ample inlet for the flow ofwater thru the opening.

A still further object of my invention is to provide a funneled section,each section having means to seat an adjacent section thereonconcentrically, and means to attach 3 the sections so that the adjacentend portions will lap vertically but be spaced apart horizontally, theupper section lapping over the lower and on the outside thereof, so thata gravel filling when placed therearound will not be inclined to freelypass thru the opening to the interior of the screen, by which means thegravel functions as a filter and spacing means for the wall of the wellfrom.

40 the screen which is axially positioned therein. These and otherobjects will hereinafter be more fully explained, reference being had tothe accompanying drawing forming a part of this specification, and inwhich like characters will apply to like parts in the different views,and in which V Fig. 1 is an elevation of the lower portion of a wellpartly in section showing the screen r with a gravel filling therearoundand an outer casing partly pulled upward.

. Fig. 2 is an enlarged plan view of one of the'screen sections.

Fig. 3 is a sectional view taken on line 3-3 in Fig. 2', the said Viewshowing two of the screen sections assembled. v

My invention herein disclosed consists of a funneled section comprisinga side wall 1 having afiange A on the upper endthereof and a pluralityof lugs 2 spaced therearound and integral therewith, each lug having a 9bearing B on which the wall 1 will rest, and a shoulder G and'a tongueportion 1) downwardly extending and to seat on the offset above theshoulder C, and being secured thereto by a pin 3 engaging in an aperturein the tongue and the lug.

"A series of screen sections thus arranged will stack in axial alignmentproviding an opening as at E between the adjacent ends thereof, and theadjacent end portions will lap so that'gravel as shown at 4 will notfreely pass therebetween while being filled to the upper extent as shownin Fig. 1. The gravel functions as acfilter against soil or fine sand Fpassing therethru withithe flow ofwater to the interior of the screen.

In assembling my screen structure, aplate 5 which is disc like in formis attached to the lower end of the bottom screen member so and being soarranged, a better footing is provided for the weight of the componentparts of the well casing as a whole.

Secured to'the top member of the screen is a flange union 6 threadedlyengaging on a casing 7 the casing extends to the surface or top of thewell and in which is placed the suction pipe of a pump, the-latter notbeing shown in the drawing.

In Fig. 1 is shown a casing 8 employed while drilling a well, the saidcasing being lowered as the drill descends, and when the desired,quantity of water is encountered, the pipe 7 with our screen arrangementsecured to the lower end thereof in the manner previously described islowered into the wall. I then proceed to fill with gravel as shown inFig. 1 and withdraw the casing 8 as the fill- I ing is made,the gravelbeing the supporting means for the'w'all should the same be m- 199clined to cave or wash freely, and in all instances the gravel mustextend upward the full length of the screen and further if so desired.The filling above the screen may be sand which of course is at thediscretion of the workman installing the same.

It will be understood that the filling in contact with the screen willimpose a pressure thereon, and to resist such I have arranged a flangemember A as previously described integral with the smaller end of thesection, the other end having its bearing on the lugs as at C, the saidlugs being spaced apart and fitting snugly with the tongue portion ofeach succeeding section is reenforcing'means for the lower end thereof.

It is now readily seen how I am able to construct the funneled wall verythin which is the means to reduce excess weight and eX- pense in eachsection and the assembling of the screen.

Such modifications may be employed as lie within the scope of theappended claim, and having fully described my invention, what I claim asnew and desire to secure by Letters Patent is In a water well screen, amember having an annular flanged funneled wall, the flange inwardlyextending and integral with the small end of the funneled wall andfunctioning as a reenforcement therefor, and a seat for a flange unionof a casing, lugs spaced around the funneled wall, the lugs transverselyextending across the wall, each lug having a tongue longitudinallyextending and aligned therewith, means to connect the tongue with thelug of an adjacent funneled wall, by which means the said walls areaxially aligned and attached, substantially as shown.

In testimony whereof I afiiX my signature.
